Abstract
The present invention relates to a mobile communication system, and more particularly, to a method of adjusting a signal power in a variable data rate mode. Accordingly, the present invention includes steps of allocating a reference pilot signal level to each of a plurality of data rates supported by the system and adjusting the reference pilot signal level for a changed data rate based on an external control information and adjusting a power control threshold for secondly adjusting the reference pilot signal level corresponding to the reference pilot signal level.

A method of adjusting a signal power in a variable data rate mode of a mobile communication system, comprising:
- allocating a reference pilot signal level to each of a plurality of data rates supported by the system;
- determining a data rate based on an external control information;
- transmitting a data rate information corresponding to the determined data rate;
- adjusting a power control threshold that is compared with the reference pilot signal level to generate a value of a power control bit for controlling the reference pilot signal level;
- and
- adjusting the reference pilot power signal level based on the determined data rate.
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- classifying data rates supported by the communication system into a predetermined number of groups;
- allocating a reference pilot signal level to each of the data rates;
- reporting a change of the data rate group to a different group if a changed data rate based on an external control information is the highest or lowest data rate among the data rates which a group includes;
- adjusting a power control threshold for adjusting the reference pilot signal level after transmitting a change-approval message in response to the reporting;
- and
- adjusting the power of the pilot signal corresponding to the changed group after receiving the approval message.
